Calcium Tungstate is a Perspective Acousto-Optic Material

Acousto-optic modulators are main component of communication fibre-optic systems. From the other side the studies of the absolute piezo-optic effect (POE) are one of the important steps to estimate the acousto-optic efficiency of optical materials.The investigation results of POE in calcium tungstate crystals (CaWO4) has been represented. It is also proved that this crystal is essentially better acousto-optic material in comparison with lithium niobate (LiNbO3) widely used in acousto-optic devices.
